Method Detail

loadModel

@Nullable
public static SModel loadModel(@NotNull
                               String content)

Try to load a model using a default ModelFactory identified by extension from supplied textual content.

Returns:

null if fails to load model from the content supplied (either model read error, no model factory for the extension, or factory doesn't support textual content)

loadModel

@Nullable
public static SModel loadModel(byte[] content,
                               @NotNull
                               ModelFactory factory)

Try to load a model using ModelFactory from supplied content.

Returns:

null if fails to load model from the content supplied (either model read error) or loaded model from the byte array content using the supplied model factory

loadBinaryModel

@Nullable
public static SModel loadBinaryModel(byte[] content)

loadModel

public static SModel loadModel(@NotNull
                               IFile file)

saveModel

public static String saveModel(SModel model,
                               String extension)

saveModelToXml

public static org.jdom.Element saveModelToXml(SModel model)

loadModelFromXml

public static SModel loadModelFromXml(org.jdom.Element element)

saveBinaryModel

public static byte[] saveBinaryModel(SModel model)

modelContentAsStream

public static InputStream modelContentAsStream(SModel model,
                                               String extension)

Serialize model with a persistence identified by extension and provide access to serialized content through InputStream.

Returns:

empty stream in case serialization failed. Caller is responsible to close the stream.

savePerRootModel

public static String savePerRootModel(SModel model,
                                      String name)

savePerRootModel

public static String savePerRootModel(SModel model,
                                      boolean isHeader)
